Call me boring, but several years ago when I had a 9.3X62 built, I wanted loads for 250s and 286s.
JBs 250 load was either RL15 or Varget for 2650 fps. With the Accubond his RL15 load went easily under MOA and ten shots averaged 2647 fps with tiny velocity spread in my rifle.
With 286 NPs, his 65-66 grains of Big Game for a supposed 2475 fps? In my rifle 66 grains clocks 2470 fps and shoots inside the 250 grain load. Better accuracy and same point of impact.
As far as seating depth, my rifle has a bullet diameter but longer European type throat so I couldn't measure off the lands like I normally do. So I simply seated them both to OALs typical for the 3.38" mag box.
Load development DONE.
Unless a guy loves chasing handloading minutiae for entertainment value, which I get, why complicate things?
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
